Be it known that I, ALBnnr A. GRANOV- snr, a citizen of the Unitedl States, and

resident of the borough and county of Bronx, city and Statev of New York, have invented certain new and useful Improve; ments in Vei'minproof Mattresses, set` 'forth in the following speciiieation.

This invention relates to box bed spring construction. The object o the invention is both to simplify the con'structionl olf suelta structure and to produce one which is' ab-A solutely vermin proof and which stays vermin proof in'use. Tothese ends, a minimum of wood training is contemplated and the coordinati/on, of a simple wooden frame with al1-unbroken' undersurfaceto'serve as one jaw of clamping means to seal themargins of a covering and a bottom cover of ticking through the medium of a supporting strip forming the other jaw.

v The above and further objects or the .in vention will be set forth more particularly in the claim which is directed for purposes of illustration' to they illustrative embodiments of the invention described in the following speciication in connection with` the accompanying drawings which form part hereof. The disclosure of the illustrative embodiments herein is merely for purposes Fig. 6 is a cross-section throughfthe plane of line VI-VI ot Fig. 5;

Fig. 7 is a View corresponding tov Fig. 5, vshowing a. modification; and

Fig. 8 is a similar View showing-another modification.

A strong rectangular wooden frame A Vpreferably.having morticed corners l, as

indicated in Fig. 6, is provided'and fabricated so that its bottom face 2 throughout is an unbroken smooth surface, preferably Extending message ef this tiene nl is a series of. cross-slatset suitably secured at their ends 5 te the frame A. Mounted apen and upwardly entendingdroni 'the' sl'fitssl are rows ofeoinpression springs G reacting between the slats. and the mattress pei-tien 7 which may be of usual haiisstuffed consti-nc tion o1' oty any' other usual malte-111i; Ai cov-f ering B ot ticking, imperiorate'throughout and v errnntght, estendscver tli'eentiretop and sides-of the strne'turewith its' margin 8 underlappin" and lying' flat againstthe-het.

tom face 2 o the frat-ne' A-, to-wliicl'it may be independently secarse by series of tacks 9. This iseasy or acceinplshinent with the structure placed upside down-for the fabi-fi# cation and requires noenpensive traine struction. The opening inthe trame A isy then covered by 'a stretched cover C of ticking with its margin l0 secured to the bottom :tace of the frame A in asuitable manner as by a series of tacks 11. l/Vithl the covering B and the bottom cover Athus secured, thev covering and cover are well held mechanically in position, but are not vermin tight. Furthermore, they are far fromr being protected against accidental injury at their margins to increase the 'size of vermin openthat the locality of the margins, as for eX- ample, the irregular opening l2 between the margins 8 and l0, be smeared with a sea-ling dope such as melted resin, hot glue, paraffin, or the like. There is thenpreferably applied, so as to overlap a portio-n of both margins '8 and 1.0, aprotective bridging strip. This may be a half-round wooden bead D as shown in Figure 3,suitably secured as by brads 14 so as to clamp the intermediate fillingA of dope 15 tightly upon both margins 8 and 10 and into the space therebetween. 1When the bead Dis employed', it shouldy be mitered at the corners and the dope iilled linto* the mitered joints..

Again, it desired, metal strips D may be substituted tor half-round bead D,. in

It desired also, the sideedges 2l and 22 of such a inetal'strip maybe bent upwardly as shown in Figure 6, the better to coniine* 'the 'dope filling 15. f

Again, if desired, a continuous D, as shown 1n Figure 7,1nay be employed,

ings. To remedy this feature, it ispreferred metal strip i which-case double rowsV of brads 16 andl 17 f y shown in Figure 8, this strip may have a double fold 24 so as to make a square' corner.

In this construction, the reinforcing memvbers I), D', etc., serve the dual function of completing the vermin seal between the i covering and the cover and also serve as a mechanical resistant support for the entire construction, the sealing dope and the margins of the covering and cover being gripped between the smooth unbroken surface of the frame and this reinforcing strip. It is also contemplated that for some purposes the interposition of the dope filling may be done away withyor serve as the means for securing the strip without brads or tacks. Y

The inventive thought may have a variety of expressions as is contemplated by what I claim and desire yto secure by United States Letters Patent as follows:

A vermin proof box bed-spring construction comprising an open rectangular bottom frame having a smooth unbroken bottom face; a series of cross-slats extending crosswise of said frame and secured relatively thereto leaving the bottom face of said frame as an unbroken smooth surface; a top mattress portion spaced apart from said slats; compression springs reacting between said slatsand said v` mattress portion; a vermin tight cover of ticking covering said mattress portion, the sides of the structure and overlapping a portion of the said unbroken bottom face of said frame with its margin securedl thereto; a bottom cover of ticking stretched lacross the opening of said frame and having itsmargin overlapping a portion of said bottom face of said vframe and being secured thereto; a combination supporting strip 'and vermin seal overlapping both the margin Lof said cover of ticking and said bottom cover forming a vermin seal therewith and extending down to form a mechanically resistant `support for the entire structure and itself located wholly inside of the outer edges of the sides of the structure.

In witness whereof, I have signed my name to this specification this 12th day of June, 1924.'
